What happens in Chapter 6 of The Immortal Life of Henrietta Lacks?
Chapter 6 tells the story of how HeLa cells were scaled up in the early 1950s to meet the urgent demand for a polio vaccine. The National Foundation for Infantile Paralysis finances a large-scale cell-production operation at the Tuskegee Institute, where technicians produce tens of thousands of HeLa culture tubes to be used for testing Jonas Salk's experimental vaccine. Skloot describes the assembly-line efficiency of the Tuskegee lab: workers dressed in sterile gowns pipetting, incubating, and shipping vials of Henrietta's cells to research facilities across the country and eventually to labs around the world. HeLa cells are particularly well-suited for this purpose—they are robust, divide quickly, and are susceptible to poliovirus, making them perfect for assessing the vaccine's effectiveness. Meanwhile, Henrietta has passed away and is buried in an unmarked grave in Clover, Virginia, with her family completely unaware that her cells have become central to one of the twentieth century’s major public health successes. Skloot skillfully contrasts these two realities: the joyful scientific advancements above ground and the quiet erasure of the woman who lies beneath.
Analysis
Skloot's most effective technique in this chapter is her use of structural irony without any editorializing. She depicts the Tuskegee production facility—a site steeped in the history of medical racism—as the birthplace of HeLa's global spread, allowing the geographic and institutional choice to resonate without overtly stating its implications. The chapter picks up speed to reflect the factory rhythm it describes; sentences become shorter and more procedural when listing lab steps, then expand into longer, reflective cadences when the narrative shifts back to Henrietta's unmarked grave. This tonal shift is a hallmark of Skloot's style throughout the book, but here it is at its most concentrated and, consequently, most impactful.
The theme of invisibility deepens: HeLa cells journey around the world in refrigerated boxes, while Henrietta's name is nowhere to be found on them. Skloot also seriously introduces the theme of commodification—cells are counted, packaged, and priced, turning biological material into an industrial product. The Tuskegee backdrop subtly evokes the reader's awareness of the syphilis experiments, embedding HeLa's origin story within a wider context of Black bodies serving white medical interests without consent or recognition. The triumph of science (the polio vaccine will save millions) remains intact, yet it becomes more complex: progress and exploitation are shown to be not opposites but co-authors of the same narrative.
Key quotes from Chapter 6
“HeLa cells were one of the most important things that happened to medicine in the last hundred years.”
Skloot quotes a researcher reflecting on HeLa's role in the polio trials, anchoring the chapter's central tension between scientific achievement and unacknowledged human cost.
“The Tuskegee Institute began mass-producing HeLa cells the same year the government began its infamous syphilis study there.”
Skloot places the HeLa factory within Tuskegee's fraught institutional history, letting the juxtaposition indict without argument.
“Henrietta's cells were being grown and shipped all over the world, while her family didn't even know her cells were still alive.”
This line crystallizes the book's governing irony—global biological presence paired with total familial erasure—and appears near the chapter's close as a quiet, devastating pivot.
